[s-cars] speed nut

[Jerry Scott]

I 'm looking for the part number for the plastic speed nut that holds 
the plastic cover over the dryer in front of the firewall.  There are 
two 1/4 turn plastic fasteners that hold it on. This is the cover that 
contains the vacuum/boost line that goes to the CPU.  The nut has split 
and the local Audi dealer could not find it on their fish plate. Does 
anyone have this number handy?
Thanks,
Jerry
